Tighter restrictions for visiting Sipadan

Sabah Parks has put stricter controls on diving at Sipadan island in an effort to better protect the island’s sensitive ecosystem.

The coral reef has degraded slowly over time and the intensity or frequency of diving needs to be retained, Sabah Parks director Maklarin Lakim said in a statement to Malay Mail.

Effective 1 October 2022, one permit will only allow two dives, instead of three, per day. However, divers who have already purchased dive packages and registered with Sabah Parks will still be permitted three dives at Pulau Sipadan, instead of two.

All the Trimmings: Tips to Improve Your Efficiency in Water with Good Trim

With good trim, divers are more efficient and can stay longer and safer underwater.

Trim is a misunderstood, and often poorly rectified, scuba skill.

Francesco Cameli offers insight and advice in how to improve your trim and increase your efficiency in the water.

Fish behaviour affected by exposure to crude oil

The 3.19 million barrels of crude oil that spilled into the Gulf of Mexico during the Deepwater Horizon in 2010 had a devastating impact to the natural environment, as well as the people and animals in the vicinity.

A study on the mahi-mahi in the nearby waters revisits the incident by studying how fish in the wild are being affected from the exposure to crude oil.

The ship that tried to warn the Titanic has been found

The British merchant steamship SS Mesaba sent a warning radio message to the Titanic on April 15, 1912 while crossing the Atlantic. The message was received by the Titanic – which was advertised as unsinkable – but did not reach the main control centre of the vessel.

Later that night, the supposedly unsinkable Titanic hit an iceberg and sank on her maiden voyage, taking 1,500 lives and becoming the world’s most infamous shipwreck.

New satellite tag tracks long-term whale behaviour

Keeping an eye on whale behaviour is not easy, considering the fact that they travel vast distances and spend the majority of their time beneath the ocean surface.

To counter this, researchers at Oregon State University {OSU) have developed a new satellite tag that can track the whales' movements, even during dives.

Known as RDW, this new technology incorporates pressure and accelerometer sensors, thus giving the researchers the opportunity to monitor the whales’ movements underwater for several months.

Ancient shipwreck reveals a lost age of Mediterranean trade

According to the archaeologists, despite the religious tensions in the area, the shipwreck demonstrates that commerce was still thriving since it carried products from all over the Mediterranean, including Cyprus, Egypt, Turkey, and the coast of North Africa.

It was around the time the largely Christian Byzantine Empire was in decline and had begun losing its grip on this eastern Mediterranean region while Islamic rule was extending its reach.
